Yes they have.
I went to MClaren delership in London and the sales lady was kind enuff to show me the 2003 one ( made in 2002 ).
They have new ceramic brake pads, interior is more comfy, a nice optional rear view cam, and few gizmos.
Engine remains same ..I think little higher low end torque refinement.
However at 890k euros, who the hell is gonna buy one ?
This one
OWNZ the MAclaren
At 200K euros, I rather get the above swedish beast than a BMW crappy V12 Maclaren.
